>
> Introduced by HIVE-11634. The original idea in HIVE-11634 was to remove the
> IN partition conditions from the predicate list since the static dynamic
> partitioning would kick in and push these predicates down to metastore.
> However, the check is too aggressive and removes events such as below :
> {code}
> - Select Operator
> - expressions: UDFToDouble(UDFToInteger((hr / 2)))
> (type: double)
> - outputColumnNames: _col0
> - Statistics: Num rows: 1 Data size: 7 Basic stats:
> COMPLETE Column stats: NONE
> - Group By Operator
> - keys: _col0 (type: double)
> - mode: hash
> - outputColumnNames: _col0
> - Statistics: Num rows: 1 Data size: 7 Basic stats:
> COMPLETE Column stats: NONE
> - Dynamic Partitioning Event Operator
> - Target Input: srcpart
> - Partition key expr: UDFToDouble(hr)
> - Statistics: Num rows: 1 Data size: 7 Basic stats:
> COMPLETE Column stats: NONE
> - Target column: hr
> - Target Vertex: Map 1
> {code}
